Fountains of Wayne had it right when they said Stacy's mom has got it going on, but it looks like the memo failed to reach Stacy's mom herself who is currently undergoing bizarre rituals in an effort to look younger.

Rachel Hunter, who played every teenage boy's dream in the video for the 2003 chart-topper, came to prominence in the early 90s when she appeared on the cover of the Sports Illustrated Swimsuit Issue, and despite no longer modelling, the New Zealand-born star still possesses a keen interest in the world of beauty.

As part of her television show, Tour Of Beauty, the 46-year-old former model is allowing therapists from around the world to perform a myriad of beauty rituals on her.

Taking to Instagram this week, Rachel shared her experience of an Asian treatment, and it looks pretty uncomfortable.

The treatment removes the fine hairs from a woman's face with the help of a neck razor – all in an effort to open pores and assist the absorption of moisturiser – and must be repeated every three weeks so as to avoid the emergence of stubble.
 

Uploading a video of herself looking mildly uncomfortable as the blade edged towards her eye in the 'Japan Episode', Rachel wrote: "Having a shave. No I didn't grow any stubble. But I have to say my skin felt amazing."

"Just some of the amazing experiences I had from superfoods to ancient remedies, on wellness , longevity on @rachelstourofbeauty #beauty #beautycare," she added.

Instagram users were quick to comment on the upload, with many enquiring into the after-care procedure and others offering their opinion on the treatment.

"Discussed this with Japanese woman here in Sydney," wrote one follower. "She said her mum does this. She said to her mum "You're crazy for shaving", and her mum replied "You're crazy for not shaving". We all have our own version of normal."

Too true…but we don't think we'll be trying it any time soon.
